Code-as-Monitor: Constraint-aware Visual Programming for Reactive and Proactive Robotic Failure Detection

Computer Vision and Pattern Recognition
Automatic detection and prevention of open-set failures are crucial in closed-loop robotic systems. Recent studies often struggle to simultaneously identify unexpected failures reactively after they occur and prevent foreseeable ones proactively. To this

Comparative Benchmarking of Failure Detection Methods in Medical Image Segmentation: Unveiling the Role of Confidence Aggregation

Medical Image Anal.
Semantic segmentation is an essential component of medical image analysis research, with recent deep learning algorithms offering out-of-the-box applicability across diverse datasets. Despite these advancements, segmentation failures remain a significant

Data-Driven Gearbox Failure Detection in Industrial Robots

IEEE Transactions on Industrial Informatics, 2020
Gearbox failures cost thousands of lost production hours in plants that use industrial robots. In this context, an automated monitoring system that can warn the user of an impending failure can save precious resources.

An adaptive failure detection protocol

Proceedings 2001 Pacific Rim International Symposium on Dependable Computing, 2002
The detection of process failures is a crucial problem system designers have to cope with in order to build fault-tolerant distributed platforms. Unfortunately, it is impossible to distinguish with certainty a crashed process from a very slow process in a purely asynchronous distributed system.

On failure detection by inversion techniques

2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004
This paper considers the failure detection and reconstruction problem, for linear time invariant systems, with generalized solutions based on left inverse techniques.

An autonomic failure-detection algorithm

ACM SIGSOFT Software Engineering Notes, 2004
Designs for distributed systems must consider the possibility that failures will arise and must adopt specific failure detection strategies. We describe and analyze a self-regulating failure-detection algorithm that bounds resource usage and failure-detection latency, while automatically reassigning resources to improve failure-detection latency as ...

A review of the environmental factors degrading the performance of silicon wafer-based photovoltaic modules: Failure detection methods and essential mitigation techniques

Renewable & Sustainable Energy Reviews, 2019
The energy yield from the solar photovoltaic plant mainly depends on available solar flux, quality of the related power-conditioning equipment incorporated in the system, technical specifications of the panel, the geographic location and also on the ...

Enforcing perfect failure detection

Proceedings 21st International Conference on Distributed Computing Systems, 2002
Perfect failure detectors can correctly decide whether a computer is crashed. However it is impossible to implement a perfect failure detector in purely asynchronous systems. We show how to enforce perfect failure detection in timed distributed systems with hardware watchdogs.
